Message from the President of the IEEE Magnetics Society

Dan Stancil
Data Storage Systems Center
Carnegie Mellon University

The Magnetics Society plays a key role in supporting engineers and scientists working in applied magnetism. The Society is able to function because of the hard work and dedication of members who volunteer their time. In this first message as president, I would like to specifically thank several people who have recently stepped down after years of service to the Society.

Prof. C. D. Graham of the University of Pennsylvania has just completed six years as chairman of the Conference Executive Committee (CEC). This committee coordinates the policies and schedules for conferences sponsored by the Society, and selects sites for future INTERMAG Conferences. Conference sponsorship is one of the most visible and important of our activities, and Chad's capable leadership has been greatly appreciated. As chairman, he was widely respected for his breadth of experience and international perspective. I am grateful that Dr. Bob Fontana of the IBM Almaden Research Center has agreed to be the new chairman of the committee. Bob also has a wide range of conference experience, and I look forward to the continued effectiveness of the the CEC under his leadership.

At the conclusion of 1996, Dr. Dan Gordon completed six years as chairman of the Nominating Committee. This committee presents nominations for membership in the Administrative Committee, and nominations for officers of the Society. Clearly, the work of this committee is critical for maintaining the vitality of the Society. This is only the most recent of many contributions that Dan has made over the years, including having served as President of the Magnetics Society. I am pleased that Prof. Bill Doyle of the Center for Materials for Information Technology at the University of Alabama has agreed to be the new chairman of this committee. Bill is also a Past-President of the Society.

Finally, I would like to thank Dr. Jim Opfer for his service as president of the Society for the past two years. Because of his able leadership, the Society is well on the way to economic health, and its technical vitality has never been better. He also significantly raised our awareness to trends that could impact the future operation of the Society, such as electronic publishing.

As president, I would like to continue to strengthen the Society financially, and to encourage the development of a long-range plan. This plan would enable us to be proactive with respect to areas such as membership strength, internationalization, and electronic publishing. To this end, I have asked Prof. Ed Della Torre, Vice President, to serve as chair of the Planning Committee. Over the next few months, this committee will be considering a strategic plan for the future of the Society. I will discuss some possible opportunities for the Society in future columns. I would also welcome your ideas. You may contact me at

Alan F. Shugart Honored with Information Storage Award at Intermag '97

The 1996 IEEE Reynold B. Johnson Information Storage award was presented to Alan F. Shugart by IEEE President Joseph Bordogna, at the plenary session of Intermag '97 in New Orleans, Louisiana. The citation which accompanies Mr. Shugart's award reads:

"For leadership in the evolution of disk drive technology".
"For contributions to research, development, and
commercialization of magneto-optic recording media and
drive systems".

This award was established by the IEEE Board of Directors in 1991 and may be presented annully "for outstanding contributions to the field of information storage, with emphasis in the area of computer storage".

The award is named in honor of Reynold B. Johnson, a pioneer in magnetic disk technology, who was founding manager of the IBM San Jose Research Engineering Laboratory in California.

The award consists of a bronze medal, a certificate, and $5000. It is sponsored by IBM Corporation. Past recipients of the Information Storage Award are John M. Harker (1993), C. Dennis Mee (1994), James U. Lemke (1995), and Nobutake Imamura (1996).

Previous to the establishment of the IEEE Reynold B. Johnson Information Storage Award, the IEEE Magnetics Society presented the Magnetics Society Information Storage Award. Winners of this award were Sidney M. Rubens (1987), Jay W. Forrester (1988), Reynold B. Johnson (1989), M. Camras (1990), Charles H. Coleman (1991), and Claude Shannon (1992).

Alan F. Shugart has more than 40 years of experience in the technology industry and continues to play a key role in shaping its future. Since founding Seagate Technology, Inc. in 1979, Mr. Shugart has built the company into one of the world's largest independent manufacturers of disk drives and related components, as well as a leading developer of tape drives, software tools and applications in the area of data management, including information management, network and systems management and storage management. Mr. Shugart had the insight to combine the cost effectiveness of the flexible drive with the capacity potential of rigid disk technology, producing products that matched the format and interface of existing personal computers. This enabled use of substantial application programs and established a hardware base that launched an industry explosion. He led the industry shift from the 14-inch standard drive form factor to the 5.25-inch form factor which enabled the migration to even smaller sizes seen in the market today.

From 1975 to 1979, Mr. Shugart worked as a private consultant to the technology industry. In 1973 he co-founded Shugart Associates, the pioneer of the 5.25-inch floppy disk drive, which was critical to the first widely successful personal computer, the Apple II. From 1969 to 1973, Mr. Shugart was at Memorex where he held the position of vice president of product development. Prior to his time with Memorex, Mr. Shugart spent 18 years with IBM Corporation, starting as a field engineer in 1951, the day after he finished college. He managed a variety of programs including IBM's 2321 data cell drive; design team 1301, which developed the first modern disk drive with air bearing heads; and IBM's 305 "RAMAC", the first rigid disk drive.

Beginning in 1984, Mr. Shugart was one of the initiators of university storage research centers, encouraging more advanced training and research in the data storage field. He was also an initial sponsor of the Center for Magnetic Recording Research at the University of California at San Diego at the Data Storage Systems Center at Carnegie Mellon University, both centers of excellence in information storage research. This commitment continues worldwide today with research and development sponsorships at universities in the United Kingdom and Singapore, as well as the United States.

A California native, Mr. Shugart attended the University of Redlands where he received a Bachelor of Science degree in engineering and physics.

Gordon R. Slemon Honored with Achievement Award

The 1997 Magnetics Society Achievement Award was awards to Professor Gordon R. Slemon of the University of Toronto during the Plenary Session at the 1997 INTERMAG Conference in New Orleans, Louisiana USA.

Professor Slemon was born in Bowmansville, Ontario, Canada. He received his B.A.Sc. and M.A. Sc. degrees in Electrical Engineering from the University of Toronto. His advanced degrees are from Imperial College in London, and a Ph.D. and D.Sc. degree from the University of London, in Electrical Engineering and Engineering, respectively. He holds an honorary Doctorate from the Memorial University, St. John's, Newfoundland. His employment has been primarily with educational institutions, starting as a lecturer at the Imperial College in London and moving through the ranks on his return from England to Canada, first as an Assistant Professor at the Nova Scotia Technical college in Halifax and then as Associate Professor and since 1964 as a Professor of Electrical (and Computer) Engineering at the University of Toronto.

From 1966 to 1976 he served as a Head of the Department of Electrical Engineering and from 1979- 1986 as Dean of the Faculty of Applied Science and Engineering at the University of Toronto.

Gordon Slemon's contributions to electrical engineering education are outstanding. Gordon, as Head of the Department, guided Electrical Engineering through the transition from being primarily a small teaching department to one with an international reputation for excellence in research.

Gordon Slemon has maintained a very active research program throughout his career. It is perhaps most notable that even during those periods when he was intensively involved with university administration, he still managed to find time for his research. His interests have largely been related to the development of basic theory and models for polyphase machines, including permanent magnet synchronous machines, and the application of these machines in controlled drive systems. He has published widely on these topics, commencing with a paper that was published by the American Institute of Electrical Engineers in 1949, and today has a career total of over 160 journal publications and technical reports, many of which have appeared in the Transactions on Magnetics. The quality of his publications has always been exemplary, as evidenced by Prize Paper Awards given him by the IEEE Industry Applications Society in 1986, 1987 and 1988. During the early to mid-1970s, Gordon Slemon led the University of Toronto team that developed the linear synchronous motor and drive system for the Canadian MAGLEV project. More recently, he has focussed his research on problems relating to the design and application, in drive systems, of permanent magnet synchronous machines. He is a widely recognized expert on the design and modelling of polyphase machines and regularly participates, by invitation, in IEEE short courses on this subject. In recognition of his lifetime research contributions, Gordon Slemon has received numerous awards, most notably the IEEE Nikola Tesla Award in 1991 and an honorary Doctorate from Memorial University, Newfoundland, in 1994.

Gordon Slemon was a superb lecturer, particularly on the topics of magnetic devices and electric machines. An ongoing theme in his lectures was the insistence that students appreciate the scientific basis of the engineering principles and applications that they were studying. Many of his ideas, particularly with regard to device and system modelling, were incorporated in the several texts that he authored or co-authored, starting with The Scientific Basis of Electrical Engineering (1961; co- authored with Prof. James M. Ham), as well as Magnetoelectric Devices - Transducers, Transformers and Machines (1966), Electric Machines (1980; co- authored with Prof. A. Straughn), Power Semiconductor Drives (1984; co-authored with Profs. S. B. Dewan and A. Straughn) and, most recently, Electric Machines and Drives (1992). These texts extended his influence well beyond the several thousand undergraduate students that had the pleasure of being taught by Gordon at the University of Toronto.

Gordon Slemon has given much of his time to the IEEE Magnetics Society, as a member of the Administrative Committee for many years, on numerous Magnetics Society Committees, on the Editorial Board of the Transactions on Magnetics, on the Awards Committee which he chaired at one time. Gordon brought the INTERMAG Conference to Toronto in 1974 and was the Canadian Chair. Gordon has also participated in numerous other activities, varying from membership in major IEEE committees to the chair of the Canadian Academy of Engineering of which he is also a Fellow. In addition to the Tesla Award and the Honorary Doctorate he has also won the Western Electric Award for Engineering Education; Ross Medal, Engineering Institute of Canada; Centennial Medal, Institute of Electrical and Electronics Engineers; George Sinclair Award, University of Toronto; Canadian Engineering Educator of the Year Award; Inducted, Engineering Hall of Distinction, University of Toronto; American Society for Engineering Education Centennial Certificate; among others, and has long been a Fellow of IEEE.

Prof. Slemon is the 16th recipient of the Achievement Award. Previous winners are:
